How are granulators classified? – Suzhou Polytime Machinery Co., Ltd.

With the rapid development of the plastic industry and a large number of plastic products, the amount of waste plastics is also increasing. The rational treatment of waste plastics has also become a worldwide problem. At present, the main treatment methods of waste plastics are landfill, incineration, recycling, and so on. Landfill and incineration not only can not recycle waste plastics but also aggravate the pollution to the environment. Waste plastic recycling not only protects the environment and saves resources, but also meets the strategic requirements of China's sustainable development. Therefore, the waste plastic recycling granulator machine has a great development space.

How are granulators classified?
The common granulator used in waste plastics is divided into Foam granulator, soft plastic granulator, rigid plastic granulator, special plastic pelletizer, etc. The foam plastic granulator is, as the name suggests, a machine specially designed to produce waste foam particles. The soft plastic granulator aims at the recycling of waste woven bags, films, plastic bags, agricultural land films, drip irrigation belts, and other soft plastics. The hard plastic granulator is mainly aimed at the recycling of waste plastic pots and barrels, household appliance shells, plastic bottles, automobile bumpers, and other hard plastics. Of course, some special raw materials need special granulators, such as cross-linked polyethylene granulators, special triple granulators for paper mill waste, and so on.

What is the process flow of the granulator?
There are two methods of plastic recycling granulation: wet granulation and dry granulation.

Wet granulation is a mature processing technology through five processes: waste plastic collection, crushing, cleaning, dehydration, and granulation. When the wet granulation process is adopted, the waste plastics need to be broken after being collected, and the obtained plastic fragments are massive, then cleaned and dehydrated, and finally melt granulation.

Because the wet granulation process has high processing costs, poor recovery economic benefit, and environmental pollution, there is also a commonly used granulation process in the market, which is the dry granulation process. The dry granulation process goes through four processes: waste plastic collection, crushing, separation and granulation. The process flow is simple and the operation cost is low. However, the impurities in the separated waste plastics are difficult to be completely removed, so the purity of the finished products is reduced and can only be used to produce some low-quality plastic products, with low economic benefits.

What are the characteristics of granulator?
The plastic granulator has the following characteristics.

1. All recycled materials can be produced without drying or drying after classification, crushing and cleaning, and can be used for both dry and wet.

2. It is automatic from raw material crushing, cleaning, feeding to making particles.

3. Make full use of the high-pressure friction uninterrupted heating system to automatically heat production, avoid continuous heating, save power and energy.

4. The split automatic power distribution system is adopted to ensure the safe and normal operation of the motor.

5. The screw barrel is made of imported high-strength and high-quality carbon structural steel, which is durable.

The development and progress of waste plastic recycling equipment such as granulators can not only solve the pollution problem but also solve the current situation of the shortage of plastic resources in China and promote the development and progress of China's plastic industry.
